Solid dosing systems

There is no doubt that if the consumption of reagents is so high and their handling and preparation so complex, it is worth buying the powder chemical and preparing reagents in the field, since no one is willing to pay for large amounts of water plus the chemicals transported in tanks to the operation places of mining companies. Under this premise, DYNAFLUX S.A.  represents SODIMATE a French company specialized in the extraction and dosing of powdered products, especially fine powder, where other extraction systems do not obtain good results.

One of the most common systems in silo discharge is the vibrating bottom with an alveolar valve and endless conveyor. This system works with granular products (grain or sand type), but does not work properly with fine powder products such as lime, flocculant, CMC, activated charcoal, calcium carbonate, etc.

The main problem with pulverulent silo products is the formation of vaults in the cone (a vault is understood as the caking of the product in the form of a semicircle above the cone of the silo). The formation of vaults in the silo is inevitable and only a system that breaks the vaults can be installed.
